Chronometric dating, also known as chronometry or absolute dating, is any archaeological dating method that gives a result in calendar years before the present time.Archaeologists and scientists use absolute dating methods on samples ranging from prehistoric fossils to artifacts from relatively recent history.This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils (like those of the dinosaurs alleged to be millions of years old).This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers.The basis for stratigraphy seems quite intuitive today, but its applications were no less than earth-shattering to archaeological theory.For example, JJA Worsaae used this law to prove the Three Age System.

In other words, artifacts found in the upper layers of a site will have been deposited more recently than those found in the lower layers.Before this, archaeologists and scientists relied on deductive dating methods, such as comparing rock strata formations in different regions.Chronometric dating has advanced since the 1970s, allowing far more accurate dating of specimens.I study how bone tissue, growth, and metabolism evolve at macroevolutionary time scales. Archaeologists use many different techniques to determine the age of a particular artifact, site, or part of a site.
